Overview of the CEMS-PRE100
The CEMS-PRE100 is engineered to deliver precise, real-time monitoring of temperature, pressure, and flow rates in flue gases. It consists of two main units: the pressure and temperature unit and the chassis unit. This configuration efficiently manages complex data, providing users with precise and actionable insights for industrial processes.
Working Principles
Temperature Measurement
The CEMS-PRE100 uses a platinum resistance temperature sensor to measure temperature changes. This sensor converts temperature variations into an electrical current signal (4-20 mA) proportional to the actual temperature. The process involves filtering, amplification, non-linear correction, and V/I conversion, ensuring stable and accurate data output.
Pressure Measurement
The CEMS-PRE100 utilizes a high-precision isolation membrane pressure sensor for pressure measurement. This sensor is coupled with a specialized conversion circuit, allowing it to accurately convert detected pressure changes into a proportional electrical current signal (4-20 mA).
Flow Rate Measurement
For flow rate measurement, the CEMS-PRE100 employs a Pitot tube flow meter. The system includes an “X” type Pitot tube probe and a pressure tube housing. It functions by detecting the difference between dynamic and static pressures within the gas flow. This data is then converted into a flow rate proportional current signal (4-20 mA), providing detailed insights into the gas flow dynamics.
Internal Structure of the Device
Pressure and Temperature Unit
The pressure and temperature unit of the CEMS-PRE100 consists of a temperature sensor, “X” type Pitot tube probe, and static pressure probe. This unit focuses on collecting temperature, pressure, and flow rate signals, ensuring the device’s high accuracy and reliability.
Chassis Unit
The chassis unit is integral to the CEMS-PRE100. It contains the temperature transmitter, pressure transmitter, flow rate transmitter, and backflush control solenoid valve. This unit is responsible for converting, processing, and outputting signals related to temperature, pressure, and flow rate, as well as managing the air circuit backflush.
Operational Process
Measurement
- Temperature Measurement: The temperature sensor, housed in a protective casing, is inserted into the flue to detect high-temperature exhaust gases. The temperature transmitter converts this information into a proportional current (4-20 mA), which is then processed and displayed by an industrial computer (IPC).
- Static Pressure Measurement: A pressure sensor located within a protective casing detects the pressure of the flue gas. The pressure transmitter converts pressure changes into a proportional current (4-20 mA), enabling precise data analysis by the IPC.
- Flow Rate Measurement: The Pitot tube flow meter, also protected by a casing, measures dynamic and static pressure differences, converting the data into a flow rate proportional current (4-20 mA) for processing by the IPC.
Blowback
The CEMS-PRE100 features an air pressure system for blowback, which cleans the probe by removing dust accumulation. Normally, two solenoid valves are closed to allow pressure sensing. When blowback is required, these valves open to facilitate cleaning.
